Hi, Next hop should not be altered on iBGP session. Perhaps you have some issues that causes it. You can see my previous e-mail where I demonstrated that in simple setup there are no such problem. Can you take some problematic prefix and show how it looks on different directions? Like: on RS2: sh

Hi, We are using I-BGP between our RS for redundancy. Not every peer has a session with both RS, or some of them choose to keep only one session open at a time, so if we want to make sure every prefixes are propagated to every peer, we need to exchange route between the 2 RS. Regards, Noémie On

In my setup everything is ok. I made 4 namespaces for peera, peerb, rs1 and rs2 and joined them with one bridge network. Here is route views on client networks. As you can see - the next hop is ok on them. peera: bird> show route all Table master4: 192.168.2.0/24 unicast [direct1 00:49:56.0

Hi all, We are using Bird v2.0.2 as a route-server, and I have a question about the use of i-BGP sessions on a Bird RS. We have the following topology : 2 RS (RS1 and RS2) are connected to several peers, and some of those peers are connected to only one RS. In order to get the same amount of p
